A Review of Reports to CDC of Travelers Who Flew While Infectious With Pertussis From April 2013 to February 2024.
Article in Journal of public health management and practice : JPHMP. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
contextPertussis is endemic worldwide, and exposure can occur anywhere, including commercial aircraft. Travelers exposed to an infectious person with pertussis may receive post-exposure prophylaxis (PEP) for up to 21 days after exposure to decrease risk of infection. This is accomplished through the identification of infectious travelers and their aircraft contacts (a process called aircraft contact investigation [Air CIs]).
objectiveDescribe travelers reported to the US Centers for Disease Control and Prevention (CDC) who flew while infectious with pertussis and outcomes of associated Air CIs.
designCDC's Port Health Activity Reporting System (PHARS) was queried to identify reports of travelers who flew with pertussis from April 12, 2013, to February 28, 2024.
participantsIndex cases (passengers or crew members) with pertussis who traveled on commercial aircraft and their exposed passenger contacts.
main outcome measuresTraveler demographics, flight characteristics, outcome data from Air CIs.
resultsThree hundred and eight individuals who recently traveled on commercial aircraft with pertussis were identified. Of the passengers determined to be infectious on the flights, Air CIs were initiated for 102/270 (38%) travelers who flew on 163/500 (33%) flights. Among the 337/500 (67%) flights for which Air CI was not initiated, the most common reason was that the index case was seated adjacent to only household members (142/337, 42%). For flights in which Air CIs were initiated, 234 contacts were identified, and one secondary case in a non-household passenger contact was reported. The average time from when contacts were exposed during the flight to when a health department reported the index case to CDC was 11.6 days (median 10.3 days, range: 0-39 days).
conclusionsTimely reporting of pertussis cases after air travel may decrease transmission risk to passenger contacts and prevent severe illness.
